Step-by-step explanation:

Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.

What is a rectangle?

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

To calculate the total length of fencing Mark needs to surround all four gardens, we first need to determine the perimeter of one rectangular garden.

The perimeter of a rectangle is given by the formula:

P = 2l + 2w,

where P is the perimeter, l is the length, and w is the width.

For one rectangular garden with a length of 60 feet and a width of 43 feet, the perimeter would be:

P = 2(60) + 2(43) = 120 + 86 = 206 feet.

Therefore, to surround all four gardens, Mark would need a total of:

4 x 206 feet = 824 feet of fencing.

Thus,

Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.

surround all 4 gardens?

The area of a rectangle is 90 square inches. Find the length and width so that the rectangle has the least perimeter. Assume that the length and width are both whole numbers​

Answers

Note: given x and y have the same product the smallest sum of x and y are if they are closer together
Thus finding the factors of 90: 1, 2,3,5,6,9,10,15,18,30,45,90. So the closest are 9 and 10

The data set, {81, 87, 71, 89}, represents Ken's test scores for the first four tests of the semester. Ken scored an 85 on the fifth test.

What impact does the 85 have on the mean test score?

Answers

Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82

Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6

The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.

Answer:

decrease

Step-by-step explanation:

If 89 is the highest score, Ken would need a score of 90+ to increase the mean.

[tex]Md < 89\\Mi >89[/tex]

Md = mean decreases

Mi = mean increases

I'm not sure if this is exactly right because the wording of the problem is confusing.

Answer:

a) Number of square feet of wallpaper for bedroom = 12x^2 - 21

b) Number of square feet of wallpaper for living room = 14x^2 - 42

c) Total amount of wallpaper needed = 26x^2 - 63

d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.

Step-by-step explanation:

a) First find the area of each wall.

Length: 3x, Width: 3x, Height: x

(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2

12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.

3 × 7 = 21

12x^2 - 21 = Total sq ft of wallpaper needed for bedroom

b) First find the area of each wall.

Length: 4x, Width: 3x, Height: x

(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2

14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.

3 × 7 = 21 × 2 = 42

42x^2 - 42 = Total sq ft of wallpaper needed for living room

c) Add the two expressions to find the total amount of wallpaper needed.

(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63

26x^2 - 63 = Total sq ft of wallpaper needed for both rooms

d) Plug x = 8 into the equations found in part a and b.

12(8)^2 - 21 = 747

14(8)^2 - 42 = 854

Subtract these answers to find the difference in amount.

854 - 747 = 107

The living room needs 107 sq ft more of wallpaper than the bedroom

Why does it say it’s incorrect-

When the 982 rounded to the nearest hundred so it comes 1000.

The following information should be relevant:

At the time of rounding off the numbers, we have to look at whether the tens digit is 5 or more or it should be less than 4 or 4.If it is 5 or more so the same should be rounded up.And, if it is 4 or less so the same should be rounded down.

Therefore we can conclude that When the 982 rounded to the nearest hundred so it comes 1000.
